TikTok getting sued for 5-9 year old on the app

TikTok is a app where you can create videos and have cool features! Over 1 billion people downloaded the app and half of the people are under that age of 13 which is the age limit to be on the app. The TikTok owner explains that kids within the age of 10-12 can be allowed and of course other ages that are older. But tons of kids have been seeing videos that are a bad influence on them. Such as cursing, doing seriously dangerous things, and a whole lot more. So TikTok is getting sued or TikTok can permanently remove the kids under that age of 10. What do you think about this?
